On Low Rate Discharge only 42.2 ampere hours were obtained owing to the one cell being faulty this showing positive weakness.
On High Rate Discharge
Initial amperes = 10.7.9
Time to 104 " = 6.4 min
" " 100 " = 9.7 "
" " 90 " = 12.6 "
" " 80 " = 18.5 "

The same cell again showed faulty & showed positive weakness on the cadmium positive 1.5 negative .2.

It will be interesting to open up this cell to find the cause of premature failure.
